-BooT AND SHOE MANUFACTURE 1 Filed May 8, 1940 Patented 0er. 21, 1941 UNITED STATES PATENT OFFICEl BOOT AND SHOE MANUFACTURE Alfred Vamos, New York., N. Y., assig'nor to Fried-` berger-Aaron Manufacturingy Company, Philadelphia, Pa., a corporation of Pennsylvania 5 Claim.

This invention is directed to an improvement in boot and shoe manufacture, and more particularly relates to the provision of an improved binding and reinforcing means for shoe uppers formed in whole or in part of stretchable material.

As disclosed in my Patent o. 2,184,261, an improved type of shoe maybe produced by making the upper in whole or part of stretchable material, in particular a stretchable plied material consisting of stretchable leather having an elastic backing.

In finishing the upper edge of such shoes around the foot opening the elastic fabric is skived away, as shown in my said patent, and the exposed portion of leather folded upon itself and stitched or cemented in place. Such construction, while furnishing a neatly rounded edge, is not wholly satisfactory in that the edge so formed is not elastic, whereas to preserve the appearance and shape of the shoe upper around the foot opening the edge portion should have even greater lelasticity than the rest of the elastic portion of the shoe.

It has also been proposed in United States Patent No. 2,184,082 to Roberts to provide'an elastic reinforcing tape for this edge portion to l increase the elasticity thereof, but this necessitates an additional operation, and detracts from the neatness of the vedge formed.

Now in accordance with this invention, I pro.- vide-a simple and expeditious means of finishing and reinforcing the raw edge of an elastic upper. I accomplish thisby providing an elastic tape precoated with a pressure sensitive cold cement in conveniently usable form, which tape may be easily-and quickly secured to the raw edge of the shoe upper aroundV the foot opening to provide a ing a step inthe application `of my improved binding;

Figure 3 is a section on the line 3--3 in Fig. 1; and ,f

Figure 4 is an enlarged view of a portionof my improved binding tape showing the elements of which it is composed.

Referring first to Fig.' 4, my improved binding 55v comprises a narrow strip 'of woven orl braided elastic webbing I having embodied therein ne elastic warp threads 3, a narrow strip of thinI paper tape 5, coated on both faces with a pressure sensitiveV cold cement composition 6, and secured by said adhesive to said webbing I so as to cover notmore than one-half the width thereof from one edge, and, if desired, a protective strip 1, of, for example, crinkled paper, overlying tape 5 and protecting the adhesive coating 6 on the exposed face thereof.

The paper tape 5, together with the protective covering 'I may conveniently be applied to a strip of webbing I by feeding the two strips; with an adhesive face of tape 5 in contact with the face of strip I, through a set of pressure rolls.

When my improved binding is to be applied to the edge of the shoe upper, which, as shown in Figs. 2 and 3, is composed of an outer layer 9 of stretchable leather and an inner layer II of elastic fabric cemented together, an edge of the webbing I will be secured to the shoe upper. by a line of stitching I3, as shown in Fig. 2. The stitching I3 may bey a zigzag stitch, or may be made with elastic thread so as not to interfere with the elasticity of the binding or shoe upper. The protective strip 'I may be left in place during this operation, as shown, or may be removed to expose the adhesive surface of. tape 5, whichever is more convenient.

Following this operation, the protective strip l will be removed, if this has not already been done, and the binding will be folded over the raw edge of the shoe upper, concealing the stitching I3, and secured to the inner face thereof by the adhesive on tape 5, asshown in Fig. 3. With certain machines this can be accomplished in almost the same operation as the stitching, the sewing mechanism-being followed by a folding and ,pressing mechanism.

The raw edge of the. elastic shoe upper will now be bound and reinforced by an elastic binding, but the presence of the inelastic tape 5 would seem to negative such elasticity. However, the

tape 5, as stated, is formed of thin paper, or.

` with elastic materials because of the various modifications therein may be made without departing from the scope of my invention. I am aware that it has been proposed to produce a shoe piping in which a textile tape coated with adhesive on both faces is secured to a leather piping strip, but such construction, while satisfactory for non-elastic shoes, could not be used v non-elasticity of the textiletape. l

What I claim and desire to protect by Letters Patent is:

l. An article of manufacture comprising an elastic shoe upper, an elastic vbinding strip, and a non-elastic tape formed of readily frangible material coated on both faces with a pressure sensitive cold cement, the strip being folded over the edge of the upper and the tape being interposed between the folded over portion of said strip and the opposite side of the upper to secure said strip to said upper.

2. An article of manufacture comprising an elastic shoe upper, an elastic binding strip, and a thin, readily frangible paper tape coated on both faceswith a pressure sensitive cold cement, the strip being folded over the edge of the upper and the tape being interposed between the folded over portion of said strip and the opposite side of the upper to secure said strip to said upper.

3. An elastic binding tape for binding and restrip of elastic fabric, and a non-elastic tape formed of readily frangible material coated on both faces with a pressure sensitive cold cement overlying said strip along one margin thereof and secured thereto by means of the cement coating on one face of said tape.

4. An elastic binding tape for binding and reinforcing elastic shoe uppers comprising a narrow strip of elastic fabric. and a thin, readily frangible paper tape coated on both faces with a pressure sensitive cold cement overlying said strip along one margin thereof and secured thereto by means of the cement coating on one face.

5. An elastic binding tape for'binding and reinforcing elastic shoe uppers comprising a narrow strip of elastic fabric, a non-elastic tape formed of readily frangible material coated on both faces with a pressure sensitive cold cement overlying said strip along one margin thereof and secured thereto by means of the cement coating on one face of said tape, and a temporary protective covering adhered to the free face of said tape to protect the adhesive coating thereon.
